Increased interleukin-18 expression in nonrheumatic aortic valve stenosis
International Journal of Cardiology
|February 17, 2009
Summary
Interleukin-18 (IL-18) is present and active in nonrheumatic aortic stenosis (NR-AS) valves. Elevated IL-18 levels correlate with NR-AS severity, suggesting its role in the disease.
Area of Science:
- Cardiovascular Biology
- Inflammatory Mediators
- Aortic Valve Disease
Background:
- The role of interleukin-18 (IL-18) in the pathophysiology of nonrheumatic aortic stenosis (NR-AS) remains uncharacterized.
- Investigating IL-18's involvement is crucial for understanding NR-AS progression.
Discussion:
- IL-18 is expressed in human NR-AS valves, with increased levels observed compared to controls.
- The active form of IL-18 and its receptor are present in NR-AS valves, indicating potential signaling pathways.
- IL-18 expression positively correlates with the clinical severity of NR-AS.
Key Insights:
- Demonstrates the presence and upregulation of IL-18 in NR-AS valves.
- Confirms expression of the IL-18 receptor in affected valves.
- Links active IL-18 to advanced NR-AS clinical presentation.
Outlook:
- IL-18 may be a significant contributor to NR-AS pathogenesis.
- Further research into IL-18's specific mechanisms in NR-AS is warranted.
- Potential therapeutic targeting of IL-18 in NR-AS could be explored.

Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
